To all whom it may concern:

Be it known that I, WILLIAM F; CARLTON,l

a citizen of the United States, residing at Advance, in the county of Stoddard and incident to a draft or blast of air.

. pel

State of Missouri, have invented a new and useful Pneumatic Grain-Conveyer, of which the following is a specification.

This invention has relation to pneumatic grain conveyers' and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to rovide a conveyer of the character indicate( which is adapted to actuate the material in consequence of suction force and propelling force l The parts being so arranged that the grain does not come in contact with the l rotor or yother means which create the suction and propelling forces. In the present instance a fan is employed as a means for drawing andA roing an air column and as the grain oes not come in contact with thev blades of the fan the grain is not injured thereby nor does the grain wear the fan by coming forcibly in contactv therewith.

is a side` elevation of the conveyer.

Inthe accompanying drawings: Figure 1 Fig. 2 is a vertical sectional view of the same, and Fig. 3 is an elevation ofa portion of a modified form of conveyer.

The conveyer consists of the fan casing 1 in which the fan 2 is mounted for rotation. Said casing is provided with an outlet 3. A grain pipe (not shown) is connected with the opening 4 of the drum 4 which is located above the hopper 5. The lower end of said hop er communicates with the interior of the ower portion of the fan casing 1 and is lprovided with a valve 6 which normally ears at its lower edge against thel bottom of i the' casing 1 and from the casingl ermits material to pass from the' hopper 5 lnto the casin 1; naled for rotatlon in the bottom of the hoi per 5 and Vis ada ted to force material towar the valve 6.

valve 6 and is ada ted to positively force material from theliottom of the hopper 5 under the valve 6 and into the casing 1. Both the feeder'and the feed auger derive their movement from the shaft of the fan 2, v The shaft of the auger 7 is provided with a worm wheel 9 with which the worm gear 10 plrevents any back draft L t rough the hopper f5 but g The feed auger 7 is our- 1 T e rotating feeder 8 is located between the end of the feed auger 7 and the" meshes. The said gear 10 is mounted u on the shaft 1 1 as is also the belt pulley 12. he belt 13 passes around the pulley 12 and a pulley located upon the shaft of the fan 2. 'lhe feeder 8 is mounted upon the shaft 14 as is also the belt pulley 15, the belt 16 passes around the pulley 15 and a pulley mounted upon the shaft of the fan 2. The byass 17 communicates atone end with the en of the T he u per end of the said by-pass is covered with a oraminous cap 18 'which is located in the drum 4 and tions 19 which bear against the sides of the 'hopper 5 and hold the same 1n place.

lows: The fan 2 is rotated and grain is admitted into the drum 4, as the said fan rotates the air is drawn from theudrum 4 through the byass 17 into the casmg 1 and is expelled by tlie fan through the outlet y3. The suction created by the fan through the by-pass 17 augments the introduction o f the grain into the drum 4 and the foramlnous cap 18 revents any ofthe grain from enteringthe y-pass 17. Consequently, the grain that enters the drum 4 falls lnto the ho per 5 and is forced by the auger 7 toward the eeder der the valve 6 and into the casing 1 where it is caught up by the blast of air forced through the outlet 3 and is borne along with the same. Thus it will be observed that the movement of the grain is actuated by the suction and propelling forces of the fan without coming in actual contact with the fan. As the fan by-pass 17 much of the moisture carrled by the grain is removed with the air andthe grain is materially dried.

In the form of arrangement shown in Fig.

@With and t e chain of gears 20, 21 and 22 are used in lieu thereof for the purpose of trans- 4 mitting movement from the fan shaft to the i feeder shaft 14. .It will therefore appear that any desired and known means may be employed for transmitting movement from the fan shaft to the other movable parts.

Having describedmy invention` what I claim as new and desire to secure by Letters Patent isz- A conveyer comprising means for imlparting suction and propelling forces to a co umn of air, means for separating material from which is provided with the depending secf The operation of the conveyer 1s as foldrum 4 and at its opposite end with the air0 inlet of the fan casing 1..

8. The said feeder forces the said grain unremoves the air from the grain-through the 3 the belt ulley 15 and belt 16'are dispensed i A l other.
